Ability to create a material that hides specific body parts, and to save one aspect of a material and add it to another material with out replacing the material all to gather
Layers in the material room

I'm not sure what you mean, because there is a way to do at least part of what you want. Say you want to hide the forearm. Select the forearm and go into the group tool and it should be selected. Choose "assign material", rename "New Material" to "forearm", and close the group tool. Now go into the material room and select the forearm. Change transparency and edge transparency to 1, and every other material value to 0 to create an "invisible" material. Now your forearm will not show in rendered images. To bring it back, just copy the material from another part that used the same material the forearm used before.

And you can do this with any selection of faces, doesn't have to be an entire body part. Just don't give faces with different materials the same material if you'll need to change them back later.
